Active deployment
Mansa S.A.
At Mansa S.A., I define technical standards for hybrid trading platforms — React, React Native, and Flutter clients consuming live market data over WebSockets with sub-100ms latency. I lead Design System adoption, Clean Architecture, and CI/CD across web, desktop, and mobile.
“Performance-critical interfaces where risk mitigation is part of the architecture, not an afterthought.”
Before fintech, I led marketing operations at scale and built hands-on security research in homelab environments — network traffic analysis, penetration testing, and threat detection on Kali and Ubuntu VMs. That dual lens shapes how I ship: performance-critical interfaces where risk mitigation is part of the architecture, not an afterthought.
